Answer: 1 Since 5 is a prime number, the only possible common factors are 1 and 5. Because 18 is not divisible by 5, the only common factor, and thus the greatest common factor, is 1.

No, the Greatest Common Factor (GCF) of 5 and 18 is 1, so the fraction 5/18 can't be reduced.

The greatest common factor of 90 and 216 is 18 90 = 2 * 32 * 5 216 = 23 * 33 greatest common factor = 2 * 32 = 2 * 9 = 18 90 / 18 = 5 216 / 18 = 12 because the greatest common factor of these is 1.

The greatest Common Factor (GCF) of 18 and 75 is 3.

18. (2 x 18, 5 x 18)

Yes, they are. 5 is the only prime factor of 25 and 5 is not a factor of 18, so they have no prime factors in common, which is what relatively prime means.

The factors of 18 are 1, 2, 3, 6, 9 and 18. None of them are multiples of 5.

Just 1.
